Abstract (en)
[origin: WO2020198774A1] A description is given of a rail treatment machine able to be moved on rails, having at least one drive motor (4) and having at least one working unit (1) for treating rails, wherein a permanent energy source, an electrical energy store (3) and a current collector for providing traction current are provided in order to supply electric power to the drive motor (4) and the working unit (1), wherein the permanent energy source, the energy store (3), the current collector providing the traction current, the drive motor (4) and the working unit (1) are connected to a common DC grid (9) via converters. In order to provide a rail treatment machine able to be moved on rails that allows low-maintenance and environmentally friendly deployment of working units with greatly varying peak loads, without having to accept losses in terms of treatment quality, it is proposed for the permanent energy source to be a fuel cell (2) that feeds at least one base load of the working unit (1) into the DC grid (9) via the converter, and for buffer energy of the energy store (3) acting as buffer store to be able to be fed into the DC grid (9) via the associated converter in order to cover peak loads at least of the working unit (1).
